STAGE: The Administration Server first copies the deployment unit source files to the staging directories of  goal servers designated by way of the Staging Directory Name  characteristic.The target servers then installation the usage of their neighborhood copy

NOSTAGE: The Administration Server does now not reproduction deployment unit documents. Instead, all servers deploy the use of the same physical reproduction of the deployment documents, which have to  be at once handy via the Administration Server and  target servers. With nostage deployments of exploded archive directories,  WebLogic Server robotically detects adjustments to a  deployment's JSPs or Servlets and refreshes the deployment. 

(This behavior can be disabled if vital.)

EXTERNAL_Storage: The Administration Server does not reproduction  deployment documents. Instead, the Administrator need to make certain  that deployment documents are disbursed to the ideal  staging listing region earlier than deployment (as an instance,  via manually copying documents previous to deployment). 

With external_stage deployments, the Administration Server  calls for a copy of the deployment files for validation  functions. Copies of the deployment documents that reside in  target servers' staging directories are not validated  earlier than deployment.
